Description

  The present invention relates to a monitoring apparatus that monitors abnormalities in, for example, waterworks and sewerage processing facilities.

  Conventionally, monitoring control systems such as water treatment facilities perform monitoring by connecting a human interface device (HMI) of a supervisor and a controller (PLC) on a monitoring target side (see, for example, Patent Document 1 and Patent Document 2). .

When the PLC detects an abnormality in a control system such as a water treatment facility to be monitored, the PLC transmits a notification signal notifying the abnormality to the HMI. When the HMI receives a signal from the PLC, the HMI performs alarm processing such as screen display and audio output in order to warn the supervisor about an abnormality in the control system on the PLC side that is the transmission source of the signal.

In recent years, with the merger of municipalities and the promotion of labor saving, facilities that have been monitored in each area are often monitored collectively by a wide area monitoring control system.
In the monitoring control system, when an HMI receives a notification signal notifying an abnormality, there are cases where an alarm process needs to be performed by the HMI and there are cases where it is not.

  For example, if the time zone is at night and the alarm processing for notifying the abnormality of the control system to be monitored by the PLC that is the transmission source of the notification signal is performed, If the restoration priority is low, or if it is difficult for the monitoring staff to perform restoration work at the site of the signal transmission source, that is, the abnormality occurrence source, it may not be possible to cope with the alarm processing.

  Therefore, in the conventional supervisory control system, whether or not the HMI performs alarm processing is set for each signal input from the PLC in the HMI.

  Specific examples of the setting of the presence / absence of alarm processing include scan-off (the signal reception data itself is not updated) and monitoring off (the signal reception data is updated but the alarm processing is not performed).

  However, these settings are common to all HMIs when there are a plurality of HMIs in the monitoring center. In this case, even if the monitoring person in charge of each HMI is different, the setting of whether alarm processing is performed or not is collectively, so that appropriate information is reported to each observer, such as handling signals outside the person in charge. I can't.

  Also, when switching the alarm processing setting depending on the time zone such as daytime or nighttime, it is necessary to set the presence or absence of the alarm for each signal. turn into.

  Therefore, an object of the present invention is to provide a monitoring device that can appropriately determine whether or not to perform alarm processing related to an abnormality of a facility to be monitored depending on the situation.

  That is, the monitoring apparatus according to the present invention is a definition for defining, for each of a plurality of monitoring forms, detection means for detecting an abnormality of a monitoring target and information indicating whether alarm processing related to the abnormality detected by the detection means for the monitoring target is necessary. Information indicating that an alarm process related to the abnormality of the monitoring target of the abnormality detection source in the monitoring form that has already been set in the monitoring form that has been set is detected when an abnormality is detected. Is defined by the definition means, the alarm processing is performed on the monitoring target, and the detection means determines that the information indicating that the alarm processing is required is not defined. It is characterized in that no alarm processing is performed.

  According to the present invention, it is possible to appropriately determine whether or not to perform an alarm process related to an abnormality of a facility to be monitored depending on the situation.

Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
First, a first embodiment of the present invention will be described.
FIG. 1 is a block diagram illustrating a configuration example of a monitoring system according to the first embodiment of the present invention.
The monitoring system according to the first embodiment of the present invention includes a water purification plant monitoring device 1, 2 having a control system supervisor of a water purification facility, and a transmission device 3, which transmits an abnormality notification signal when an abnormality occurs in the control system described above. 4,5.

  Both monitoring devices 1 and 2 are installed in the monitoring room of the Z water treatment plant. The monitoring device 1 is a monitoring device handled by a supervisor who is in charge of water purification monitoring at the Z water treatment plant, and the monitoring device 2 is a monitoring device handled by a supervisor who is in charge of water distribution monitoring at the same Z water treatment plant as the installation location of the monitoring device 1. is there.

The transmission device 3 transmits to the monitoring devices 1 and 2 an abnormality notification signal that notifies the occurrence of an abnormality at the point when an abnormality occurs in the control system at the point a in the Z water purification plant premises. The transmission device 4 transmits to the monitoring devices 1 and 2 an abnormality notification signal that notifies the occurrence of an abnormality at the point when an abnormality occurs in the control system at the point b in the Z water purification plant. The transmission device 5 transmits to the monitoring devices 1 and 2 an abnormality notification signal that notifies the occurrence of an abnormality at the point c when an abnormality occurs in the control system at the point c in the Z water purification plant. Each transmitter transmits single or plural types of abnormality notification signals. The abnormality notification signal from each transmitter includes signal name information. The signal name indicates information such as the name of the facility where the abnormality occurred and the name of the installation location of the facility.
In addition, although not shown in FIG. 1, transmission devices are similarly provided at other points D and E.

FIG. 2 is a block diagram illustrating a configuration example of the monitoring device of the monitoring system according to the first embodiment of the present invention. Although FIG. 2 shows the monitoring device 1, the same applies to the monitoring device 2.
Each monitoring device includes a control unit 11 that controls the entire processing operation, a storage device 12 that is a nonvolatile memory, a signal receiving unit 13, an abnormality source determination unit 14, a notification presence / absence determination unit 15, a notification processing unit 16, a keyboard, a mouse, and the like. Input device 17, display device 18 such as a display device, monitoring mode switching unit 19, and audio output unit 20 such as a speaker, which are connected to each other via a bus 21.

The signal receiving unit 13 inputs an abnormality notification signal from each transmission device including the transmission devices 3, 4, and 5.
The abnormality source determination unit 14 determines the signal name of the abnormality notification signal received by the signal reception unit 13.

  The notification presence / absence determination unit 15 determines whether or not the signal name determined by the abnormality source determination unit 14 is the signal name of the alarm processing target. The alarm process is an alarm process for notifying the monitor of the abnormality at the abnormality occurrence source indicated by the signal name, and is displayed on the display device 18 for highlighting the abnormality at the abnormality occurrence source to the supervisor. It is a voice output process by the process and the voice output unit 20.

  When the notification presence / absence determination unit 15 determines that the signal name described above is the signal name of the alarm processing target, the notification processing unit 16 performs an alarm process regarding the abnormality occurrence source indicated by the determined signal name. When the notification presence / absence determining unit 15 determines that the signal name is not the signal name of the alarm processing target, the normal display processing regarding the abnormality at the abnormality occurrence source indicated by the determined signal name is performed without performing the alarm processing. In the normal display process, there is no audio output process as compared with the alarm process, and the abnormality occurrence source indicated by the signal name is displayed small at the lower part of the screen of the display device 18, for example.

  The monitoring mode switching unit 19 switches the monitoring mode by the monitoring device 1 in accordance with an operation on the input device 17. In the present embodiment, the monitoring mode can be individually set in each of the monitoring devices.

FIG. 3 is a diagram illustrating a configuration example of the notification classification information managed by the monitoring device of the monitoring system according to the first embodiment of the present invention in a table format.
The storage device 12 includes a notification classification information storage unit 22. The notification classification information storage unit 22 stores notification classification information for managing the identification name of each monitoring mode and the alarm target signal name in association with each other. Signals of alarm target signal names “A” to “E” shown in FIG. 3 are signals transmitted from the transmission device 3 shown in FIG. 1, and signals transmitted from the transmission devices 4 and 5 have signal names “ Signals other than “A” to “E”.

  When the signal name of the abnormal communication signal is included in the alarm target signal name in the monitoring mode associated with the notification classification information, the notification presence / absence determination unit 15 determines that the alarm processing related to the abnormality occurrence source indicated by the signal name is necessary, If it is not included, it is determined that alarm processing relating to the abnormality occurrence source is unnecessary.

  In the present embodiment, the monitoring mode is divided into a water purification monitoring mode and a water distribution monitoring mode. The water purification monitoring mode is a mode that is set when the supervisor in charge of the monitoring device, that is, the supervisor in charge of alarm processing by the alarm processing, is in charge of the water purification monitoring. The water distribution monitoring mode is the monitoring of the supervisor who handles the monitoring device. This mode is set when the field in charge is water distribution monitoring.

  In the notification classification information shown in FIG. 3, when the current monitoring mode is the water purification monitoring mode, the signal names “A” and “B” in which the signal name of the abnormality notification signal is defined as the alarm target signal name for the water purification monitoring mode. ”,“ E ”, or the like, the abnormality occurrence source indicated by the signal name is an alarm processing target, and the signal name is not a signal name defined as an alarm target signal name for the water purification monitoring mode. Indicates that the abnormality occurrence source indicated by the signal name is a normal display processing target.

  In the notification classification information also shown in FIG. 3, when the current monitoring mode is the water distribution monitoring mode, the signal name of the abnormality notification signal is defined as “C”, “D” as the alarm target signal name for the water distribution monitoring mode. , “E”, etc., when the abnormality occurrence source indicated by the signal name is an alarm processing target and the signal name is not a signal name defined as an alarm target signal name in the water distribution monitoring mode. Indicates that the abnormality occurrence source indicated by the signal name is a normal display processing target.

  In the example illustrated in FIG. 3, the signal names “A” and “B” are signal names determined as alarm target signal names only for the water purification monitoring mode, and are not included in the alarm target signal names for the water distribution monitoring mode. . The signal names “C” and “D” are signal names determined as alarm target signal names only for the water distribution monitoring mode, and are not included in the alarm target signal names for the water purification monitoring mode.

  That is, in the case where the signal name of the abnormality notification signal is a signal name determined as an alarm target signal name only for the water purification monitoring mode, the alarm processing accompanying reception of the signal is only performed by the monitoring device whose monitoring mode is the water purification monitoring mode. When the signal name of the abnormality notification signal is the signal name determined as the alarm target signal name only for the water distribution monitoring mode, the alarm processing accompanying the reception of the signal is performed only by the monitoring device whose monitoring mode is the water distribution monitoring mode. Made.

  In addition, when the signal name of the abnormality notification signal is a signal name determined as an alarm target signal name in both the water purification monitoring mode and the water distribution monitoring mode, the alarm processing associated with reception of the signal is the monitoring mode in the water purification monitoring mode. This is done both on certain monitoring devices and on monitoring devices that are in the water distribution monitoring mode.

  In addition, since the notification category information stored in the notification category information storage unit 22 of the storage device 12 can be updated by an operation on the input device 17, the signal name to be monitored is added due to equipment enhancement or the like. It is possible to easily cope with the case.

FIG. 4 is a diagram illustrating a first display example of a monitoring mode setting screen displayed by the monitoring device of the monitoring system according to the first embodiment of the present invention.
FIG. 5 is a diagram illustrating a second display example of the monitoring mode setting screen displayed by the monitoring device of the monitoring system according to the first embodiment of the present invention.
When the monitor operates the input device 17 of each monitoring device to be handled according to a predetermined procedure, a monitoring mode setting screen is displayed on the display device 18. On the mode setting screen, an icon written as “clean water monitoring mode” and an icon written as “water distribution monitoring mode” are displayed.

  As shown in FIG. 4, when the “clean water monitoring mode” icon on the screen is selected by an input operation using the input device 17, and the OK icon displayed on the screen is selected, the monitoring mode switching unit 19 displays its own device. Information indicating that the monitoring mode is the clean water monitoring mode is stored in the storage device 12.

  As shown in FIG. 5, when the “distribution monitoring mode” icon on the screen is selected by an input operation using the input device 17 and the OK icon displayed on the screen is selected, the monitoring mode switching unit 19 Information indicating that the monitoring mode of the own device is the water distribution monitoring mode is stored in the storage device 12. This completes the setting of the monitoring mode.

Next, the operation of the monitoring system having the configuration shown in FIG. 1 will be described. FIG. 6 is a flowchart illustrating an example of a processing operation performed by the monitoring device of the monitoring system according to the first embodiment of the present invention. Here, the processing operation of the monitoring apparatus 1 will be described.
First, when the signal receiving unit 13 of the monitoring device 1 receives a single or a plurality of types of abnormality notification signals from the transmission devices including the transmission devices 3, 4, and 5 (step S1), the abnormality source determination unit 14 The signal name of the received abnormality notification signal is determined (step S2).

  The notification presence / absence determination unit 15 reads the current monitoring mode information from the storage device 12 and recognizes it (step S3). Then, the notification presence / absence determination unit 15 reads the notification category information from the notification category information storage unit 22 of the storage device 12 (step S4), and the signal name determined by the abnormality source determination unit 14 in the notification category information is the process of step S3. Whether or not the signal name of the received abnormality notification signal is the signal name of the alarm processing target by determining whether it is included in the alarm target signal name associated with the identification name of the monitoring mode that has been recognized in Is discriminated (step S5).

  A specific example of the process in step S5 will be described. When the current monitoring mode is the purified water monitoring mode, “A”, “B”, and “E” are included in the notification target information in the example shown in FIG.

  In this case, when the signal name of the received abnormality notification signal is “A”, since the signal name is included in the alarm target signal name related to the current monitoring mode, the notification presence / absence determining unit 15 uses the signal name. It is determined that the indicated abnormality occurrence source is an alarm processing target (YES in step S5).

FIG. 7 is a diagram illustrating a first display example of the abnormality notification screen displayed by the monitoring device of the monitoring system according to the first embodiment of the present invention.
In this case, the notification processing unit 16 generates a large message window indicating the abnormality source abnormality indicated by the signal name “A” and displays it in the center of the screen on the display device 18 as shown in FIG. Alarm processing for generating an alarm sound or message indicating an abnormality at the abnormality occurrence source and outputting it to the audio output unit 20 is performed (step S6). When the icon displayed as “Confirm” on the screen is selected by operating the input device 17, the message window is closed.

FIG. 8 is a diagram illustrating a second display example of the abnormality notification screen displayed by the monitoring device of the monitoring system according to the first embodiment of the present invention.
On the other hand, when the signal name of the received abnormality notification signal is “C”, the signal name is not included in the alarm target signal name related to the water purification monitoring mode that is the current monitoring mode. Determines that the abnormality occurrence source indicated by the signal name is not an alarm processing target (NO in step S5).

  In this case, the notification processing unit 16 does not perform the alarm processing described above, generates a small message window indicating an abnormality at the abnormality occurrence source indicated by the signal name “C”, and displays on the display device 18 as shown in FIG. A normal display process for displaying at the bottom of the screen is performed (step S7).

  As described above, in the monitoring system according to the first embodiment of the present invention, for each signal name, which is the installation location of the transmission apparatus, whether or not alarm processing is required when an abnormality notification signal is received from the installation location is determined for each monitoring mode. When an error notification signal is received, if the signal name of the signal corresponds to the name of the alarm target signal in the current monitoring mode, alarm processing that indicates an error at the error source indicated by the signal name is performed. On the other hand, if it is not applicable, no alarm processing is performed.

  Therefore, if a monitoring person who handles each monitoring device sets a monitoring mode related to his / her monitoring field with the monitoring device of the handling destination, only the information that needs to be grasped as an abnormality occurrence source in the monitoring field is displayed 18. And the voice output unit 20 can clearly grasp.

On the other hand, if the abnormality occurrence source indicated by the abnormality notification signal does not need to be recognized as an abnormality occurrence source in the field in charge of monitoring, alarm processing is not performed. Therefore, it is not necessary for the monitor to confirm whether or not the abnormality occurrence source displayed on the screen is an abnormality occurrence source that needs to be grasped in the field in charge of monitoring.
That is, the monitoring staff can monitor the presence or absence of an abnormality that needs to be grasped, but does not need to monitor the presence or absence of an abnormality that does not need to be monitored.

  And for each monitoring device, when the monitoring system of each signal changes and the monitoring person in charge of the monitoring device changes, or another monitoring person who has a different monitoring field changes the monitoring device. Even if it is to be handled, if the monitoring mode corresponding to the monitoring field in charge of the monitoring person who handles the monitoring device is set, it becomes possible for the monitoring person to continuously monitor the presence or absence of only the necessary signal. Therefore, it is possible to save labor for monitoring work by the supervisor and to eliminate the complication of work.

  In addition, monitoring personnel in various areas in charge of monitoring can perform appropriate monitoring by setting the monitoring mode related to their own monitoring area for the monitoring devices to be handled among multiple monitoring devices. There is no need to determine the installation location of the target monitoring device.

  Although there are two types of monitoring modes described in the present embodiment, the number of types is not limited as long as there are a plurality of modes. For example, a monitoring target by a water purification monitoring supervisor and a monitoring target by a water distribution monitoring supervisor at night A night monitoring mode may be further provided for collectively monitoring important monitoring targets. In this case, if the night monitoring person switches the monitoring mode to the night monitoring mode, the above-described night-time monitoring target can be monitored without distinction between the water purification monitoring person and the water distribution monitoring person already described.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In addition, description of the same part as what was shown in 1st Embodiment among the structures of the system between the following each embodiment is abbreviate | omitted.
FIG. 9 is a block diagram illustrating a configuration example of a monitoring system according to the second embodiment of the present invention.

And transmitters 3, 4, and 5 for transmitting an abnormality notification signal when an abnormality occurs in the control system at each point described above.

  The monitoring device 31 is installed in a monitoring room of the Z water treatment plant, and the monitoring device 32 is installed in a monitoring office away from the Z water treatment plant. The monitoring device 31 is a monitoring device handled by a Z water purification plant monitor, and the monitoring device 32 is a monitoring device handled by a monitoring office monitor.

  In this embodiment, the monitoring work is shared between the Z water purification plant and the monitoring office in the daytime and at night. Specifically, at the Z water treatment plant, the monitor performs the monitoring work only in the daytime, and the monitor switches the monitoring mode in the monitoring device 31 to the daytime monitoring mode at the start of the daytime monitoring work, When the daytime monitoring operation ends and the night comes, the monitoring mode of the monitoring device 31 is switched to the nighttime monitoring mode.

  Further, in the monitoring office, a monitoring person performs monitoring work using the monitoring device 32 only at night, and the monitoring person switches the monitoring mode in the monitoring apparatus 32 to the night monitoring mode at the start of the night monitoring work. Thus, when the nighttime monitoring operation is finished and it is daytime, the monitoring mode of the monitoring device 32 is switched to the daytime monitoring mode.

FIG. 10 is a diagram showing a configuration example of the notification classification information managed by the monitoring device of the monitoring system according to the second embodiment of the present invention in a table format.
In this embodiment, the monitoring mode is divided into a daytime monitoring mode and a nighttime monitoring mode. The daytime monitoring mode is a mode that is set when the time zone in which the monitoring person handles the monitoring device is daytime, and the nighttime monitoring mode is the mode that is set when the time zone in which the monitoring person handles the monitoring device is nighttime.

  In the notification classification information shown in FIG. 10, when the current monitoring mode is the daytime monitoring mode, the signal names “A” and “B” in which the signal name of the abnormality notification signal is defined as the alarm target signal name for the daytime monitoring mode. ”,“ C ”,“ D ”,“ E ”, etc., the abnormality at the abnormality occurrence source indicated by the signal name is an alarm processing target, and the signal name is an alarm for the daytime monitoring mode. If the signal name is not a signal name defined as the target signal name, it indicates that the abnormality at the abnormality occurrence source indicated by the signal name is a normal display processing target.

  Further, in the notification classification information shown in FIG. 10, when the current monitoring mode is the night monitoring mode, the signal name “A”, the signal name of the abnormality notification signal is defined as the alarm target signal name for the night monitoring mode, If it is “D”, “E”, etc., the abnormality at the source of the abnormality indicated by the signal name is the alarm processing target, and the signal name is determined as the alarm target signal name for the night monitoring mode. If it is not a signal name, it indicates that an abnormality at the abnormality occurrence source indicated by the signal name is a normal display processing target.

  In the example shown in FIG. 10, the signal names “A” and “B” are signal names determined as alarm target signal names only for the daytime monitoring mode, and are not included in the alarm target signal names for the nighttime monitoring mode. . The signal names “C”, “D”, and “E” are signal names defined as alarm target signal names for both the daytime monitoring mode and the nighttime monitoring mode.

That is, when the signal name of the abnormality notification signal is a signal name determined as an alarm target signal name for only the daytime monitoring mode, the alarm processing accompanying reception of the signal is performed only by the monitoring device whose monitoring mode is the daytime monitoring mode. Made.
In addition, when the signal name of the abnormality notification signal is a signal name determined as an alarm target signal name for both the daytime monitoring mode and the nighttime monitoring mode, the alarm processing associated with reception of the signal is performed in the daytime monitoring mode. Some monitoring devices and monitoring devices in which the monitoring mode is the nighttime monitoring mode are made.

FIG. 11 is a diagram illustrating a first display example of a monitoring mode setting screen displayed by the monitoring device of the monitoring system according to the second embodiment of the present invention.
FIG. 12 is a diagram illustrating a first display example of a monitoring mode setting screen displayed by the monitoring device of the monitoring system according to the second embodiment of the present invention.
When the monitor operates the input device 17 of each monitoring device to be handled according to a predetermined procedure, a monitoring mode setting screen is displayed on the display device 18. On the mode setting screen, an icon denoted as “daytime monitoring mode” and an icon denoted as “nighttime monitoring mode” are displayed.

  As shown in FIG. 11, when the “daytime monitoring mode” icon on the screen is selected by an input operation using the input device 17 and the OK icon displayed on the screen is selected, the monitoring mode switching unit 19 sets its own device. Information indicating that the monitoring mode is the daytime monitoring mode is stored in the storage device 12.

  As shown in FIG. 12, when the “night monitoring mode” icon on the screen is selected by an input operation using the input device 17 and an OK icon displayed on the screen is selected, the monitoring mode switching unit 19 Information indicating that the monitoring mode of the own device is the nighttime monitoring mode is stored in the storage device 12. This completes the setting of the monitoring mode.

Next, the operation of the monitoring system having the configuration shown in FIG. 9 will be described. Here, the processing operation of the monitoring device 31 on the Z water purification plant side will be described. FIG. 13 is a flowchart illustrating an example of a processing operation performed by the monitoring device of the monitoring system according to the second embodiment of the present invention.
First, the processing from step S1 to step S4 described in the first embodiment is performed, and the notification presence / absence determination unit 15 is a signal determined by the abnormality source determination unit 14 in the notification classification information that has been read in the processing of step S4. By determining whether the name is included in the alarm target signal name associated with the current monitoring mode, it is determined whether the signal name of the received abnormality notification signal is the signal name of the alarm processing target .

  A specific example of this determination will be described. When the recognized monitoring mode is the nighttime monitoring mode, the notification presence / absence determining unit 15 uses “C”, “D”, and “D” in the example shown in FIG. “E”.

  In this case, when the signal name of the received abnormality notification signal is “C”, the signal name is included in the alarm target abnormality signal name related to the current monitoring mode, and therefore the abnormality occurrence indicated by the determined signal name occurs. It is determined that the original is an alarm processing target. Then, the process of step S6 described in the first embodiment, that is, the alarm process regarding the abnormality at the abnormality occurrence source indicated by the signal name “C” is performed.

  On the other hand, when the signal name of the received abnormality notification signal is “B”, the notification presence / absence determination unit 15 has already determined because the signal name is not included in the alarm target abnormality signal name related to the current monitoring mode. It is determined that the abnormality occurrence source indicated by the signal name is not an alarm processing target. Then, the process of step S7 described in the first embodiment, that is, the normal display process regarding the abnormality at the abnormality occurrence source indicated by the signal name “B” is performed.

  After the normal display process, the notification presence / absence determination unit 15 stores information on the signal name that is the target of the normal display process among the signal names of the received abnormality notification signals in the storage device 12 (step S11).

  When the monitoring mode switching unit 19 switches the monitoring mode again in accordance with an operation on the input device 17 (step S12), the notification presence / absence determining unit 15 stores the information on the signal name held in the process of step S11. (Step S13).

  Then, the notification presence / absence determination unit 15 recognizes the current monitoring mode information by reading it from the storage device 12 in the same manner as the process of step S3. Then, the notification presence / absence determining unit 15 reads the notification category information from the notification category information storage unit 22 of the storage device 12, and the signal name read out in the process of step S13 is associated with the recognized monitoring mode in the notification category information. By determining whether or not the alarm target signal name is included, it is determined whether or not the abnormality occurrence source indicated by the signal name of the received abnormality notification signal is the alarm processing target. Then, an alarm process or a normal display process related to the abnormality of the abnormality source signal indicated by the signal name of the abnormality notification signal is performed based on the determination result by the notification presence / absence determining unit 15.

  As described above, in the monitoring system according to the second embodiment of the present invention, for each signal name that is a location where the transmission device is installed, whether or not alarm processing is required when an abnormality notification signal is received from the location is indicated by the alarm target signal name. For daytime monitoring mode and nighttime monitoring mode, and when receiving an abnormality notification signal, if the signal name that is the source of the signal corresponds to the alarm target signal name in the current monitoring mode, the signal name The alarm processing indicating the abnormality at the abnormality occurrence source indicated by is performed, and if not applicable, the alarm processing is not performed.

  Therefore, the monitor who handles the monitoring device 31 of the Z water treatment plant and the monitoring device 32 of the monitoring office can set the monitoring mode related to the current time zone, that is, the monitoring time zone of his / her own, in the handling destination monitoring device. For example, only the abnormality occurrence source that needs to be grasped as the abnormality occurrence source in the time period can be clearly grasped by the display device 18 or the voice output unit 20.

  On the other hand, alarms are not processed for abnormalities that do not need to be grasped in the current time zone, so the monitoring staff grasps the abnormal origin displayed on the display screen as the abnormal origin in the current time zone. There is no need to check whether or not it is necessary. Therefore, as in the first embodiment, the monitor can monitor the presence / absence of an abnormality that needs to be grasped, but does not need to monitor the presence / absence of an abnormality that does not need to be monitored.

  In addition, if the number of watchdogs on duty during nighttime monitoring at the monitoring office is less than the number of daytime Z water treatment plant watchers, the night watchers will have the same number of abnormality source abnormalities as in the daytime. If you monitor, you will be forced to overload. However, in the monitoring device 32 in the monitoring office, the notification classification information is set so as to narrow down the alarm target signal names to only important signal names as shown in FIG. When an abnormality notification signal due to an original abnormality is received, alarm processing is performed only when the reception timing is daytime, so that an excessive burden is not imposed on the nighttime monitoring system.

  Further, by performing the processing after step S11 after the normal display processing, the signal name that is not the target of the alarm processing in the monitoring mode at the time of receiving the abnormal signal is an alarm when the monitoring mode is switched to another monitoring mode. If it is an object of processing, it is possible to clearly notify the monitor of the abnormality at the abnormality occurrence source indicated by the signal name.

  In the second embodiment, it has been described that the monitoring mode is switched between the daytime monitoring mode and the nighttime monitoring mode in accordance with the operation by the supervisor when the time zone is switched. Then, the monitoring mode may be automatically switched depending on the time zone to which the time measured by the time measuring device belongs.

(Third embodiment)
Next, a third embodiment of the present invention will be described. FIG. 14 is a block diagram illustrating a configuration example of a monitoring system according to the third embodiment of the present invention.
The monitoring system in the third embodiment of the present invention is a monitoring device 41 of a Z water purification plant that is an arrangement location of a water purification facility monitor, and a transmission device 3 that transmits an abnormality notification signal when an abnormality occurs in the control system described above. 4,5.
The monitoring device 41 is installed in the monitoring room of the Z water purification plant. The monitoring device 41 is a monitoring device that is shared and used by daytime monitoring personnel and nighttime monitoring personnel at the Z water treatment plant.

  In this embodiment, the monitoring work system at the Z water treatment plant is switched between daytime and nighttime. Specifically, at the Z water treatment plant, a day-time monitoring person performs monitoring work using the monitoring device 41 during the daytime, and a night-time monitoring person performs monitoring work using the same monitoring device 41 at night. ing.

  In the present embodiment, as in the second embodiment, the monitoring mode is divided into a daytime monitoring mode and a nighttime monitoring mode. Daytime monitoring mode is a mode that is set when a daytime watcher takes over monitoring work with a nighttime watcher, and the nighttime watch mode is a monitoring work between a nighttime watcher and a daytime watcher. This mode is set when taking over.

  In the third embodiment of the present invention, the notification classification information is the same as the configuration shown in FIG. 10, and the monitoring mode setting screen is the same as the screen shown in FIG. 11 or FIG. Therefore, the processing operation of the monitoring device 41 is the same as the operation of the monitoring device 31 of the Z water purification plant described in the second embodiment.

  As described above, in the monitoring system according to the third embodiment of the present invention, as in the second embodiment, for each signal name that is the installation location of the transmission device, an alarm at the time of receiving an abnormality notification signal from the location is received. Since the necessity of processing is set for each of the daytime monitoring mode and the nighttime monitoring mode with the name of the signal to be alarmed, the daytime monitoring person or the nighttime monitoring person who handles the monitoring device 41 has his / her monitoring time zone. If the monitoring mode 41 related to is set by the monitoring device 41 of the handling destination, it is possible to clearly grasp the abnormality at the abnormality occurrence source that needs to be grasped in the time zone by the display device 18 or the audio output unit 20.

  In addition, since an alarm process is not performed for an abnormality at the source of the abnormality that the monitoring staff does not need to grasp in the current time zone, the monitoring staff can display the abnormality generating source displayed on the display screen as in the second embodiment. Does not need to confirm whether or not it is necessary to grasp as an abnormality occurrence source in the current time zone.

  In addition, if the number of observers at the Z water treatment plant at night is less than the number of observers at the Z water treatment plant during the day, it will be overestimated if the observer monitors the same number of abnormalities as the daytime. However, as in the second embodiment, it is not necessary to place an excessive burden on the nighttime monitoring system.

  Further, in each embodiment, the abnormality occurrence source indicated by the signal name of the abnormality notification signal is displayed on the monitoring device in the alarm processing. The information indicating the details may be included, and the information indicating the details may be further displayed on the monitoring device side in the alarm processing.

  In each embodiment, the abnormality notification signal is transmitted from the transmission device at each point. Instead, the control device transmits various control values such as a water level and a voltage value from each point to the monitoring device. Then, the structure which detects abnormality by comparison with the transmitted control value and a reference value may be sufficient.
